Abstract

We present a trigonometric parallax for the nearby star SCR 1845-6357, an extremely red, high proper motion object discovered by Hambly et al. and identified via accurate photoelectric photometry and spectroscopy to be an M8.5 dwarf with a photometric parallax of 4.6 ± 0.8 pc by Henry et al. Using methods similar to those described in Deacon & Hambly, we have derived a full astrometric solution from SuperCOSMOS scans of eight survey and nonsurvey Schmidt photographs held in the United Kingdom Schmidt Telescope Unit plate library. We calculate the trigonometric parallax to be π = 282 ± 23 mas, yielding a distance of 3.5 ± 0.3 pc, which implies an absolute K _s, magnitude of 10.79. This distance calculation places SCR 1845-6357 as the 16th closest stellar system to the Sun.
